Inside The Altascientist: Understanding Drug Interaction Factors for Safer, More Effective Therapies

Alta Sciences

In Issue 7 of The Altascientist , we delve into these factors, the importance of drug interaction studies, and how to limit adverse effects and maximize treatment response. In some cases, these side effects could be life-threatening, such as drops in blood pressure, irregular heartbeats, or organ damage.

Factors influencing the Central Nervous System (CNS) distribution of the ATR inhibitor elimusertib (BAY1895344): Implications for the treatment of CNS tumors [Metabolism, Transport, and Pharmacogenetics]

ASPET

GBM has a poor prognosis despite aggressive treatment, in part due to lack of adequate drug permeability at the BBB. Acknowledging the potential for inter-species differences in pharmacokinetics, these data suggest that clinical translation of elimusertib in combination with temozolomide for treatment of GBM may be limited.

Pharmacokinetics of panobinostat: Inter-species difference in metabolic stability [Metabolism, Transport, and Pharmacogenetics]

ASPET

Panobinostat is a potent pan-HDAC inhibitor that has been tested in multiple studies for the treatment of brain tumors. There have been contrasting views surrounding its efficacy for the treatment of tumors in the CNS following systemic administration when examined in different models or species.

CNS distribution of panobinostat in preclinical models to guide dosing for pediatric brain tumors [Metabolism, Transport, and Pharmacogenetics]

ASPET

Panobinostat is a nonselective pan-HDAC inhibitor that is being tested in pre-clinical and clinical studies, including for the treatment of pediatric medulloblastoma, which has a propensity for leptomeningeal spread, and diffuse midline glioma (DMG), which can infiltrate into supratentorial brain regions.

Humanization of SLCO2B1 in rats increases rCYP3A1 protein expression but not the metabolism of erlotinib to OSI-420 [Metabolism, Transport, and Pharmacogenetics]

ASPET

The contrary was observed, when microsomes isolated from treatment naive animals were assessed for the OSI-420 formation after erlotinib exposure. Microsomes isolated from the treated animals were characterized for CYP3A activity using testosterone, showing higher activity in the knock-in rats.
